You can move the log files and database files to any folder that you want to create. When you move logs and database files, you may want to create the Exchsrvr\Mdbdata file structure for consistency reasons, but you are not obligated to do so. You must grant the following default permissions to the new Mdbdata folder that contains the log files and database files:•Administrators: Full Control•Authenticated Users: Read and Execute, List Folder Contents, Read•Creator Owner: None•Server Operators: Modify, Read and Execute, List Folder Contents, Read, Write•System: Full ControlNote Only assign permissions to the Server Operators group if the Exchange server is a domain controller. Otherwise, assign permissions to the Power Users group. Only domain controllers should have permissions to the built-in Server Operators group. Stand-alone and member servers should have permissions to the built-in Power Users group.You may also have to grant the following permissions to the root drive that contains the new Mdbdata folder:•System: Full ControlDuring the process of moving log files and database files, your store is temporarily dismounted. Because the store is temporarily dismounted, it is inaccessible to your users until the process is completed. Moving log files or database files invalidates all existing incremental and differential backups; therefore, make a full backup after these changes.Do not delete or rename the Old MDBdata Folder path after you move the Exchange database. If you want to delete the old MDBdata folder, make sure that the following working directory parameter in the registry points to the new location:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem Value name: Working Directory Value type: REG_SZ Value data: C:\Program Files\Exchsrvr\Mdbdata
